Preserving the Bounty: Freezing Tomatoes

Originally I was going to use one post to cover all the ways we can preserve tomatoes, but it was getting awfully long. So instead I'll beak it up into smaller chunks that are easier to chew. You're welcome!

Unlike cucumbers, there are many ways to preserve tomatoes so you can enjoy the bounty of your harvest all through the winter and spring until your next crop is ready for harvesting. We planted lots of tomatoes because we use lots of them in cooking, salads and as side dishes. Preserved tomatoes will not have the same look and texture of a fresh from the garden tomato, but if done properly, much of the flavor will be retained. 

Whether you think of them as vegetables, fruits, or berries, they taste great, are good for you, and are fun to cook with. So, lay up plenty for use throughout the year. 

Freezing Tomatoes

Tomatoes are easy to freeze. They can be frozen in many forms, depending on your intended usage. One thing to remember: their skins will become tough after freezing, so in most cases you will want to remove the skins before using the ‘maters in your cooking. You can do this easily before freezing by popping the tomato into boiling water for just 45 seconds to a minute, depending on size, fish it out and ease it into a bowl of ice water for 5-10 minutes. This will cause the skin to split and it will peel off easily; just peel it with your fingers like peeling a grape. You can then chop it into cubes, dice it, or puree it before freezing. You can freeze them whole if you like, but they take up a lot of room in the freezer this way. If you will be cutting the tomatoes into wedges, you may want to wait to remove the skins; when they thaw out the skins will slip right off. No need to fuss with blanching and icing now. 

I’m going to demonstrate freezing them in wedges because we feel this will give us the most versatility when we thaw them out again, and because it’s warm this evening and I don’t want to heat up the house more with a big pot of boiling water on the stove. 

Mess of Maters 

First, gather yourself a mess of tomatoes, a very sharp knife, cutting board and a cookie sheet. The nice thing about freezing is that they can be done in small batches with a minimum of fuss and equipment. 

Wash the tomatoes and remove the stem. I always leave the stem-stump on the tomato until we use it to prevent the stem scar from absorbing impurities from the air and while washing. When washing them, do not dump a load onto a sink full of water, again, the stem scar works like a sponge and will pull some of the dirty water into the tomato while it’s soaking. Don’t use soap. What is recommended to use is a solution of four parts water to one part vinegar. This “vegetable wash” can be used on most of your produce to kill the majority of the bacteria on the skin and greatly extend storage time of the fresh tomato on your counter or in the fridge. We do not refrigerate fresh tomatoes because it changes their flavor. Most store bought tomatoes have no flavor, so it doesn’t matter. 

Freezing Tomatoes, the First Cut 

I quarter each tomato by cutting it once along the core line, cutting out the stem scar area, then cutting across the diameter of the tomato instead of lengthwise. This exposes all of the chambers where the seedy-goop is hiding, making it easy to remove.  

Freezing Tomatoes, the second cut 

This stuff does not freeze well and adds little to the nutritional value. The “meat” of the tomato is what you’re after. If you want to be especially frugal, clean the tomatoes over a colander sitting in a bowl. This will strain out the seeds and let the juice through to the bowl. You can put the juice in a jar and refrigerate it for use in cooking or making energy drinks. Dispose of the seeds carefully… if you compost them you’ll have bazillions of baby tomato plants popping up in your compost in no time.  

Do not *wash* the seeds out of the chambers, you want the tomato to be as dry as you can get it before freezing so excess ice does not form on its surface. 

Freezing tomatoes, almost vacuum packed and ready for the freezer

Lay the wedges skin down on a cookie sheet and slide it in the freezer for a couple of hours. Once they are frozen firmly, transfer them quickly to a zip-lock freezer bag, remove as much air as possible (one of those vacuum food preservation systems would be nice) and set the bag in your deep freeze for long term storage. 

Done this way, the tomatoes don't freeze into one solid clump; you can open the bag and take out what you need as you need it. You may have to smack it around a little after extended time in the freezer, but the tomato wedges will break apart. If you tossed them into a bag as you cut them, then into the freezer they will freeze together requiring you to thaw the whole bag to use any of it. 

When freezing tomatoes in a “wet” form (chopped or pureed) bag them in sizes appropriate to your typical use. If you will be using a gallon of tomatoes each time you make soup, stew or casseroles, then by all means use the gallon bags. If smaller portions are more appropriate, use quart or pint bags to reduce storage hassles and waste after thawing. 

Alternatives

In addition to freezing tomatoes by themselves, you can prepare them in your favorite sauces, or casserole starter, and freeze that. Then all you have to do is pull out a bag, defrost, add macaroni and hamburger and you have a delicious, homemade casserole. Spaghetti and a bag of your own made from scratch sauce, a quick side salad and viola, a dinner fit for a king (or queen) in no time. 

Coming Up Next

Next time I’ll continue the exploration of preserving your tomato harvest by looking at drying them. I have a batch in the dehydrator right now, and it smells like an Italian bakery in here.   Wonderful!  We’ll also look at what you can do with dried tomatoes and explore several ways to dry them.
